       12. The device of claim 10 wherein said first aperture in said first wall member is extruded so that said first inner surface extends outwardly from said first wall member and said second aperture in said second wall member is extruded so that said second inner surface extends outwardly from said second wall member. 
     
     
       13. The device of claim 5 wherein said first and second inner surfaces each comprise a coined pattern. 
     
     
       14. The device of claim 13 wherein each said pattern comprises a plurality of coined rectangular recesses. 
     
     
       15. A blank for a terminal connector stamped from sheet metal comprising, a trunk portion having a central axis extending between first and second opposite ends,   first and second tabs at said first end being oppositely disposed and extending transverse to said central axis, said first and second tabs being adapted for forming a crimp connection to an electrical conductor,   third and fourth tabs at said second end being oppositely disposed and extending transverse to said central axis,   each said third and fourth tabs having a post-receiving aperture equispaced from said central axis on a common line transverse to said central axis, and   each said third and fourth tabs having a fastener aperture equispaced from said central axis on said line transverse to said central axis.   
     
     
       16. A battery post connector comprising a base portion for attachment to an electrical conductor,   a contact portion for engaging a battery post, said base portion and said contact portion being integrally formed stamped metal construction, said contact portion comprising a first wall member having a first aperture for receiving a battery post, and,   a second wall member having a second aperture for receiving a battery post, said second wall member being spaced from said first wall member with said first and second apertures being aligned for receiving a battery post therethrough, and     means for drawing said first wall member toward said second wall member to clamp the battery post connector to a battery post.
